Minnesota Vikings running back Adrian Peterson was booked and released from a Texas jail on a child abuse charge early Saturday, capping a tumultuous week for the NFL, which was already facing heavy criticism for its handling of a domestic violence case involving another star player.

Quarterbacks are breaking records left and right in the pass-happy NFL, but that makes high-caliber running backs all the more valuable. Many of last season’s top performers appear on this list, but keep in mind there’s usually a major bust or two, likely due to the heavy workload of the position causing a hangover effect.
